Awful to-do. A child outside gets trampled under foot (5,2)

'trampled under foot' is the definition.
'stood on' can be an answer for 'trampled'. I am not certain of the 'under foot' bit.

'awful to-do a child outside' is the wordplay.
'awful' is an anagram indicator.
'a child' becomes 'son' (male child).
'outside' indicates putting letters inside (some letters go outside others).
'to'+'do'='todo'
'todo' with letters rearranged gives 'tood'.
'tood' inserted within 'son' is 'STOOD ON'.

'gets' acts as a link.
